Bumps esbuild from 0.17.19 to 0.25.6.

Release notes

Sourced from esbuild's releases.

v0.25.6

  • Fix a memory leak when cancel() is used on a build context (#4231)

    Calling rebuild() followed by cancel() in rapid succession could previously leak memory. The bundler uses a producer/consumer model internally, and the resource leak was caused by the consumer being termianted while there were still remaining unreceived results from a producer. To avoid the leak, the consumer now waits for all producers to finish before terminating.

  • Support empty :is() and :where() syntax in CSS (#4232)

    Previously using these selectors with esbuild would generate a warning. That warning has been removed in this release for these cases.

  • Improve tree-shaking of try statements in dead code (#4224)

    With this release, esbuild will now remove certain try statements if esbuild considers them to be within dead code (i.e. code that is known to not ever be evaluated). For example:

    // Original code
    return 'foo'
    try { return 'bar' } catch {}
    // Old output (with --minify)
    return"foo";try{return"bar"}catch{}
    // New output (with --minify)
    return"foo";

  • Consider negated bigints to have no side effects

    While esbuild currently considers 1, -1, and 1n to all have no side effects, it didn't previously consider -1n to have no side effects. This is because esbuild does constant folding with numbers but not bigints. However, it meant that unused negative bigint constants were not tree-shaken. With this release, esbuild will now consider these expressions to also be side-effect free:

    // Original code
    let a = 1, b = -1, c = 1n, d = -1n
    // Old output (with --bundle --minify)
    (()=>{var n=-1n;})();
    // New output (with --bundle --minify)
    (()=>{})();

  • Support a configurable delay in watch mode before rebuilding (#3476, #4178)

    The watch() API now takes a delay option that lets you add a delay (in milliseconds) before rebuilding when a change is detected in watch mode. If you use a tool that regenerates multiple source files very slowly, this should make it more likely that esbuild's watch mode won't generate a broken intermediate build before the successful final build. This option is also available via the CLI using the --watch-delay= flag.

    This should also help avoid confusion about the watch() API's options argument. It was previously empty to allow for future API expansion, which caused some people to think that the documentation was missing. It's no longer empty now that the watch() API has an option.

  • Allow mixed array for entryPoints API option (#4223)

    The TypeScript type definitions now allow you to pass a mixed array of both string literals and object literals to the entryPoints API option, such as ['foo.js', { out: 'lib', in: 'bar.js' }]. This was always possible to do in JavaScript but the TypeScript type definitions were previously too restrictive.

Changelog

Changelog: 2023

This changelog documents all esbuild versions published in the year 2023 (versions 0.16.13 through 0.19.11).

0.19.11

  • Fix TypeScript-specific class transform edge case (#3559)

    The previous release introduced an optimization that avoided transforming super() in the class constructor for TypeScript code compiled with useDefineForClassFields set to false if all class instance fields have no initializers. The rationale was that in this case, all class instance fields are omitted in the output so no changes to the constructor are needed. However, if all of this is the case and there are #private instance fields with initializers, those private instance field initializers were still being moved into the constructor. This was problematic because they were being inserted before the call to super() (since super() is now no longer transformed in that case). This release introduces an additional optimization that avoids moving the private instance field initializers into the constructor in this edge case, which generates smaller code, matches the TypeScript compiler's output more closely, and avoids this bug:

    // Original code
    class Foo extends Bar {
      #private = 1;
      public: any;
      constructor() {
        super();
      }
    }
    // Old output (with esbuild v0.19.9)
    class Foo extends Bar {
    constructor() {
    super();
    this.#private = 1;
    }
    #private;
    }
    // Old output (with esbuild v0.19.10)
    class Foo extends Bar {
    constructor() {
    this.#private = 1;
    super();
    }
    #private;
    }
    // New output
    class Foo extends Bar {
    #private = 1;
    constructor() {
    super();
    }
    }

  • Minifier: allow reording a primitive past a side-effect (#3568)

    The minifier previously allowed reordering a side-effect past a primitive, but didn't handle the case of reordering a primitive past a side-effect. This additional case is now handled:
